Operation

9.2.1

Print unit life detection

• Based on the photo conductor driving time, the cartridge life is determined.
• When the photo conductor driving time reaches its near life, the near life warning mes-
sage appears.
• When the photo conductor driving time reaches its life time, the life warning message
appears.
• If the photo conductor runs more than its life, a life end warning message appears. When
the warning message appears, you cannot print.
• The life end message can be reset when the print unit is replaced.
9.2.2

Print unit life control

• Each print unit is provided with a PU detection board that detects state of a toner car-
tridge placement, a new PU, a print unit life.
• The main body attempts to perform a detection sequence when the front door is closed.
• When a cartridge is detected as a new one, an image stabilization sequence starts.
